Stop hooks keep agents running; sessions importable across hosts

Stop hooks can keep agent running by feeding feedback back to model instead of ending turn. Sessions can be imported and resumed from mirrored state across hosts. Auto mode continues after classifier blocks by telling agent the reason. Ctrl+B backgrounds running commands; Ctrl+G toggles tasks pane. OAuth popups in live preview redirect correctly after login. Git status shown to model at startup includes unstaged and untracked files. Minimal mode shows full reasoning in scrollback and collapses successful lookup results. Recap summaries after idle load faster by reusing previous turn's cached context.
